Abstract

The utility model discloses a coaxial cable bending tool comprising a handle and a bending positioning member connected with the handle. The bending positioning member is provided with a positioning groove used for bending and fixing a cable. The handle is a through-hole cylinder. One end of the positioning groove is in alignment with a hole in one end of the handle, and an adjusting device used for adjusting the length of a through hole is disposed in a hole in the other end of the hand. The adjusting device is locked via a locking device, the positioning groove is a square, V-shaped or arc-shaped groove, the bending positioning member is an aluminium bending positioning member, and the handle is an aluminium handle. Through the bending tool, shielding nets (outer conductors) are prevented from cracking and breaking when cable are bent, and bending positions of the cables during batch bending are good in consistency.

Description

A kind of coaxial cable bending frock

Technical field

The utility model relates to coaxial cable manufacture field, more specifically, relates to a kind of coaxial cable bending frock easy to use.

Background technology

The mobile communication equipments such as antenna of mobile communication base station, electrical tilt antenna, indoor distribution antenna, MIMO antenna are in the process of research and development trial-production and batch production, the coaxial cable using need to carry out bending and install, general existing cable bend is to adopt manual bending, but because coaxial cable bending position is approaching or close cable end conventionally, these positions are used manual bending more difficult.

Semi-flexible coaxial cable gauze screen sealing is influential to the intermodulation electrical property of antenna product, with finger extruding bending cable, easily gauze screen is destroyed and causes indiscoverable local slight crack or break, and affects the electrical properties such as intermodulation, voltage standing wave ratio; Free-hand with finger extruding bending cable, crooked circular arc and location consistency are poor; Coaxial cable has minimum bending radius requirement, and free-hand bending is difficult to guarantee bending radius; In batch production, free-hand bending cable, operator's labour intensity is high, and crooked some will cause that operator points fatigue, affects production efficiency and product quality.

Summary of the invention

In order to overcome the deficiency of the free-hand bending cable of prior art, the utility model proposes a kind of coaxial cable bending frock, while adopting this bending tool bending cable to avoid bending cable, cause gauze screen (outer conductor) occur slight crack and break, the crooked position high conformity that bending goes out in batches.

To achieve these goals, the technical solution of the utility model is:

A kind of coaxial cable bending frock, comprise handle and the crooked keeper being connected with handle, crooked keeper is provided with the detent for cable bend sizing, handle is through hole cylinder, one end of described detent is aimed at the hole of handle one end, and be equipped with for regulating the adjusting device of through hole length in the hole of the handle other end.

Further, coaxial cable bending frock also comprises the locking device for locking and regulating device, and described adjusting device is bolt, and locking device is nut.

Distance according to cable bend position from cable tail end, regulates the length of through hole by bolt, can also by the bolt of transposing different length, also regulate the length of through hole, while adjusting to correspondence position, by nut set bolt.

Different according to requirement to cable bend, detent can, for square, V-arrangement or circular arc, can be also any shape as required.

Further, described crooked keeper is the crooked keeper of aluminum.

Further, described handle is through hole cylinder, adopts cylinder as handle, holds more comfortable.

Further, described handle is aluminum handle.

Compared with prior art, the beneficial effects of the utility model are:

1) coaxial cable bending position is approaching or close cable end piece conventionally, these positions are used manual bending more difficult, when especially size is shorter, the hand cable bend of cannot holding steadily, use frock of the present utility model can utilize the moment of handle, realize normal bending cable and can also reduce labour intensity;

2) semi-flexible coaxial cable gauze screen sealing is influential to the intermodulation electrical property of antenna product, with finger extruding bending cable, easily gauze screen is destroyed to cause and be difficult to the local slight crack detecting or break, affect electrical property, the destruction that the minimum bending radius of using frock bending cable can avoid being less than cable causes;

3) use frock bending cable, crooked circular arc and location consistency are good;

4) according to different cable sizes, select different frocks, can guarantee bending radius;

5) guarantee product quality.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but embodiment of the present utility model is not limited to this.

As Fig. 1,2, a kind of coaxial cable bending frock, comprise handle 1 and the crooked keeper 2 being connected with handle 1, crooked keeper 2 is provided with the detent for cable bend sizing, handle 1 is through hole cylinder, one end of detent is aimed at the hole of handle 1 one end, and be equipped with for regulating the adjusting device 3 of through hole length in the hole of handle 1 other end, and adjusting device 3 adopts locking device 4 lockings.In the present embodiment, adjusting device 3 is bolt, and locking device 4 is nut.Distance according to cable bend position from cable tail end, by the length of bolt regulating handle 1 inner via hole, can also be by the bolt through hole length of regulating handle also of transposing different length, while adjusting to correspondence position, by nut set bolt.

As Fig. 1, crooked keeper 2 is the crooked keeper of aluminum, detent on keeper is circular arc, detent size in Fig. 1 is according to the zinc-plated cable dimension of RG141 gauze screen, if change cable size model, the cable size that can process as required amplifies and dwindles frock size, and wherein significant dimensions is the wide size 3 ~ 12mm scope choosing of detent in Fig. 2.If cable bend arc size change, only need by the φ in A-A view C diameter scope 10 ~ 60mm and φ E diameter in 13 ~ 72 size ranges, select, as Fig. 2,3.

As Fig. 4, handle 1 is aluminum handle, its size is according to the zinc-plated cable dimension design of RG141, if change cable size model, the cable size that can process as required amplifies and dwindles frock size, wherein significant dimensions be handle 1 mid diameter φ D and length L 1, L2, L3, according to cable size φ the difference of D can make series.The length L 1 of handle 1, L2, L3 are also that cable bend position length requires to make series.

As figure, 5-7 using method schematic diagrames that are this bending tool,

1) according to the crooked arc size of cable size bend, select the bending tool of detent coupling;

2) adjusting device 3 of rotoflector frock, adjusts the distance at cable bend position to suitable, as Fig. 5;

3) locking device 4 of lock adjustment device 3;

4) cable 11 is inserted to the inside, hole of handle 1, as Fig. 6;

5) holding handle 1 and utilizing frock bending cable, as Fig. 7,10 is along circular arc bending cable, and 11 is cable.If Fig. 8 is curved good cable schematic diagram.

The present embodiment utilizes handle 1 endoporus guiding to fix and bending cable, adopts the bending radius of the cable of same frock bending to equate; Cable bend position to the length of cable end piece can be adjusted by adjusting the adjusting device 3 of handle 1 end face, is conveniently applicable to the method that different length needs.

Above-described embodiment of the present utility model, does not form the restriction to the utility model protection domain.Any modification of having done within spiritual principles of the present utility model, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
